IMPROVEMENT IN LOCK-COCKS.

Specification forming part of Letters Patent No. 195,611., datedSeptember 25, 1877; application filed August 30, 1877.

To all whom it may concern:

Be it known that I, CHARLES JAEEGKI, of Erie, in the county of Erie, andin the State of Pennsylvania, have invented certain new and usefulImprovements in Lock-Cocks; and do hereby declare that the following isa full, clear, and exact description thereof, reference being had to theaccompanying drawing, and to the letters of reference marked thereon,making a part of this specification.

The nature of my invention consists in the construction and arrangementof a lock-cock, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a side elevation of myinvention, and Fig. 2 is a sectionofthe same.

A represents the body, and B the plug, of the cock, constructed in anyof the 'known and usual Ways. The plug B is provided with a handle, G,formed on or fastened to it in any suitable manner. On the under sideof' this handle is formed'a box or bearing, d, in which is placed abolt, D, which enters a` mortise, a, formed on the body A of the cock.In the drawing I have shown four of these mortises, equidistant fromeach other.

The bolt D is pressed inward by means of a spiral spring, b, surroundingthe same between the box d and a pin, e, passed through the bolt nearthe outer end, as shown. The bolt D is further provided with athumb-piece, D', so arranged as to be convenient to be operated by thethumb when grasping the handle C.

G is a lock, the hasp of which is passed through a hole in the handle,and a hole or eye formed in the end of the bolt, and thereby preventsthe cock being opened without removing the lock.

I do not confine myself to the employment of four mortises, a a, in thebody A of the cock, as the cock only needs to be locked when closed; butl prefer to have them as shown, so that it can be locked on whicheverside it may be more convenient when on the pipes.

The spring b on the bolt is not essential, as the bolt can easily bepressed by hand into the mortise. It is also unnecessary to have thelock pass both through the handle andthe hole in the end of the bolt.The same purpose can be accomplished by only having the bolt come nearthe hole in the handle. When the padlock is put on the handle the haspof the lock will then prevent the bolt from being withdrawn.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In a stop-cock, the combination, with the body A and plug B, of thehandle C projecting from the plug and provided with the sliding bolt D,one or more mortises, a, formed on the body A, and a lock, Gr, allsubstantially as and for the purposes herein set forth.

In testimony that I claim the foregoing] have hereunto set my hand this18th day oi August, 1877.

CHARLES JARECKI.
